ADSP-BF522/523/524/525/526/527
ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed in the table may cause perma-
nent damage to the device. These are stress ratings only.
Functional operation of the device at these or any other condi-
tions greater than those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device
reliability.

1 Applies to 100% transient duty cycle. For other duty cycles see Table 26.
2 Applies only when VDDEXT is within specifications. When VDDEXT is outside speci-
fications, the range is VDDEXT ± 0.2 Volts.
3 Applies to balls SCL and SDA.
4 Applies to balls USB_DP, USB_DM, and USB_VBUS.
5 For proper SDRAM controller operation, the maximum load capacitance is 50 pF
(at 3.3 V) or 30 pF (at 2.5 V) for ADDR19–1, DATA15–0, ABE1–0/SDQM1–0,
CLKOUT, SCKE, SA10, SRAS, SCAS, SWE, and SMS.

When programming OTP memory on the ADSP-
BF522/524/526 processors, the VPPOTP ball must be set to the
write value specified in the Operating Conditions for ADSP-
BF522/524/526 on Page 27. There is a finite amount of cumula-
tive time that the write voltage may be applied (dependent on
voltage and junction temperature) to VPPOTP over the lifetime
of the part. Therefore, maximum OTP memory programming
Preliminary Technical Data
time for the ADSP-BF522/524/526 processors is shown in
Table 27. The ADSP-BF523/525/527 processors do not have a
similar restriction.

The Absolute Maximum Ratings table specifies the maximum
total source/sink (IOH/IOL) current for a group of pins. Perma-
nent damage can occur if this value is exceeded. To understand
this specification, if pins PH4, PH3, PH2, PH1, and PH0 from
group 1 in the Total Current Pin Groups table, each were sourc-
ing or sinking 2 mA each, the total current for those pins would
be 10 mA. This would allow up to 70 mA total that could be
sourced or sunk by the remaining pins in the group without
damaging the device. For a list of all groups and their pins, see
the Total Current Pin Groups table. Note that the VOL and VOL
specifications have separate per-pin maximum current require-
ments, see the Electrical Characteristics For ADSP-
BF522/524/526 Processors and Electrical Characteristics For
ADSP-BF523/525/527 Processors tables.
